Home, a en of Hollench residing at county 01 Monroe and orlz, haveinvented certain res. sncl useful improvements in Breadnig lliiachines,of which the tollowing is s specification,

illlS iliYGilllOll relates to breoo cutters and s for its object toprovide an automatic an ine provided with a continuously 5g l'niie inwhich t e brez Cl is fed forin orin distance for each revolution knifeso that it wiil be cut in slices of hicitness.

also provided by which the the slices cut may be varied at eljustinentprovided therefor. .5. .th r objects of the invention will be fullyillustrated in the (ll'i'lfiiilQjE-i; described in the specification andpointed out in tlie claims at the end thereof.

The troitigh is channel shaped and the bottom of it isslightly lower than the channel 8.

The operation of the machine is as follows:

The knife may he placed across the opening in the upright .l.. The loafof bread is then placed on the channel 8 with its cud against the knife.The carriage is then brought forward into engagement with the rear endof the loaf of bread and the upper jaavis closed down on it forcing thecud of the leaf into engagement with the lower jaw, The carriage is thenengaged with the feed screw and he handwhecl is then rotated causing theloaf to he ted to the lmil e and cut in slices.

I claim:

1. In a bread cutter, the combination of a frame having a base, atraveling carriage, a feed screw for advancing said carriage, means forturning; said screw intermittently through a fixed angle, said meanscomprising a drum, a chain attached to and partially wound on said drumat one end, a rocking lever to which. the other end of said chain isattached, means for intermittently rocking said lever.

2. In a bread cutter, the combination of a frame having a base, atraveling carriage, a feed screw. for advancing said carriage, means forturning said screw intta'mitl'ently through a fixed angle, said meanscomprising' a drum, a, chain attached to and partially wound on saiddrum at one end, a rocking lever to which the other end of said chain isattached, means for intermittently rocking said lever in one direction,a spring on said drum for rocking said lever in the other di rection,said Il'lCtlllS for turning said sL-rew being adapted to rotate saidscrew in one direction by the oscillations of the drum.

3. in a bread cutter, the combination of a frame having a base, atraveling carriage, a fecdscrew toadvancing said carriage, a ratchetwheel on the end of said feed screw, a drum mounl'c d to rotate on saidfeed screw, a spring pressed pawl mounted on said drum and engaging saidratchet wheel, a chain attached to and partially wound on said drum atone end, a 1'0 king" lever to which the other end of said chain isattached, means for intern'iittcntly rocking said lever in onedirection, a spring on said drum for rocking said lever in the otherdirection, said pawl being adapted to intermittently turn said feedscrew in one direction on the oscillation of said drum by said chain.

in testimony wvhcreof I atiix my signature.
